' IMPROVEMENT IN WIND-WHEELS.

Specification forming part of Letters Patent No. 43,049, dated June 7, 1864.

To all whom it may concern:

` Beit known that l, ALFRED TRIM, of lconium, in the county of Appanoose and State of Iowa, have invented a new and Improved kvind-Wheel 5 and I do hereby declare that the following is a full, clear, and exaetde scription of the same, reference being had to the accompanying drawings, making a part of this specication,in which-f- Figure l is a side sectional view of my invention, taken in the line-.e` Fig. 2; Fig. 2, a horizontal section ofthe same, taken in the line y y, Fig. l.

Similar letters of reference indicate correspending parts in the two figures.

This invention relates to a new and improved wind-wheel, such as is placed on a vertical shaft.

The object of the invention is to obtain a wind-wheel of the class speciiied which will operate perfectly in whatever direction lthe wind may be, and one which will admit of being very readily rendered inoperative when desired, and when in operation rotate with an equal or uniform speed.

To enable others skilled in the art to fully understand and construct my invention, l will proceed to describe it.

A represents a framing, which maybe constructed in any proper manner, to support the working parts o t the device, and B is an up rightshaft in the framing A, to which shaft the wind-wheel is attached. rIhis windwheel is composed of two horizontal disks, c a', attached permanent-ly to the shaft B, and .having uprights b secured between them near their edges. rIhe disks ct a! may be described as being formed of circular plates scalloped out at their edgesto form concave recesses c, as shown clearly in Fig. 2.

C represents the wings or sails of the windwheel, which are of curved form in their horizontal section, and are attached by hinges or joints d to the peripheries of the disks ay a. 'Ihese hinges or joints may be constructed in any proper way which will admit of the wings or sails swinging freely out from and to the disks u ai', and to each wing or sail there is attached, by a cord, df, a weight, D, said cords passing through eyes c or over pulleys at the under side of the upper disk, a, near the shaft B. These weights D have a tendency to keep l the wings or sails In contact with the edges of the disks ay c. The back ends ofthe Wings or sails have arms j' attached, one at their upper and the otherjat their lower ends, and these arms prevent the wings or sails from swinging out from the disks beyond the necccessary or required distance. The arms j'. besides effecting this result, also serve, in connection with spring-catches E, to hold the wings or sails outward from the disks c a. These spring-catches E arev formedby having projections g on spring-rods li, the latter being attached to the disks c te', the outer ends ofthe rods h of each wing or sail being connected by bars t', as shown clearly in Fig. 1. Whenever a.wing or sail is forced outward from the disks a af, the arms f catch under the projections g, as will be 4understood by referring to Fig. 1. The wings or sails C may be released from the catches E at any time by adjusting a bar, F, which is attached to the framing A by a pivot, j, and has an inclined upper surface, k, over which the lower ends of the bars i pass, the latter being raised thereby,.so as to free the arms f from he projections g. (See Fig. 1.)

- G represents a shield, which is 'composed of a vertical segment or curved plate attached at its upper endto a horizontal plate, H, which turns freely on a pin, L, at the upper end of the shaft B; This plate H has an arm, m, projecting from it, to which a vane, I, is attached, andthe lower end of the segment or curved plate or shield G. may rest upon a circle or annular plate, J. The shield G is at the outer side of the wind-wheel, and at such a distance from it as just to clear the extended wings or sails, and the wind, by means of the vane I, will always keep one side of the front of the wheel covered by the shield,'so that the wind, can only act against the wings or sails at one side of the wheel, and thereby insure the rotation of the same. When the wings or sails are forced open or distcnded by the wind, they are retained in an open or eX- tended state by the catches E until the bar F is Aadjusted to release them, when they are closed by the weights D. W ithiu the wheel there are permanently-secured wings or sails K, which are also of curved form in their horizontal section, corresponding-to the cue vature of the swinging wings or lsails C, as

l shown clearly in Fig. 2.

L representsa ballgovernor, which is placed in the frai'nng Affnd has ,the...long 'arinf'n o end byl a bentleveryl vo rrneeted tofts means of a fork fitting in a groove 'in a pulley,

N, on the governor Shaft O.` Themshorharin, gn of this lever M has a shoe, P, attached to it to bear against; a-wheelVQ, on-,the Wind,

wheel shaft; B when the long'arm "u'of the -lever M is raised under the action of the governor. 'The speed of',the,'Windfwheelfis rendered uniform by means of this governor and brake, andthe long,` arm nel' the lever M has a Weight, l, uponit,vr by adjusting which the4 action of the governor upon the lever M may be regulated so as to govern the speed' of the-Wheel, as maybe '(lesi'reil. For instance, if the Weight R be adjusted near the shorty arml n of thelever, the governor `will aetuate the brake under a 'less speed of the Wheel than if the Weight were placed"nearery the governor shaft, as in the lat-ter ease' the y weight offers a greater 'resistance to the action ofthe governor. The lgovernor may be driven by -a be`l t,1S,

. from lthe Wind-Wheel shaft.
